The Jinmen (Gold) Gate was built in 1922, after the Nanxin Bridge (1921) to facilitate movement between Guanqian St and the Changmen shopping district.

However, when fighting broke out between the warlords Qi Xieyuan and Lu Yongxiang in 1923, and spread to Suzhou, the gentry felt that it would be bad to open gate and walled it off with bricks. The new Changmen Gate was put 60 meters to the south of Jinmen Gate as a direct connection with Jingde Rd.

While it seems more convenient, in fact, people had to go round about, across the Nanxin Bridge, before they could get out of town. Its position and height were not suitable so, in 1929, the city started rebuilding the Jinmen Gate, and finished in 1931.

Jinmen has three gateways and, in the Roman style, is a direct connection with the Nanxin Bridge, and, in a more curved way, with Jingde Rd.
